link-group

Function

The link-group command adds an interface to the link-group management group.

The undo link-group command deletes an interface from the link-group management group.

Format

link-group [ public ] link-group-id

undo link-group

Usage Guidelines

By default, the system is not configured with the link-group management group.

In a logical group, if one physical interface becomes faulty and changes to the Down state, all the other physical interfaces in the logical group change to the Down state. This ensures that all the physical interfaces in the logical group are in the same state.

Physical interfaces that can be added to a link-group are as follows:

GigabitEthernet interface (Subinterfaces of GigabitEthernet interface are not included.)
Eth-Trunk interface

After an Eth-Trunk interface is added to a link group, the system considers the Eth-Trunk interface to be faulty only when all Eth-Trunk member interfaces go Down.

If some interfaces are added to both the Eth-Trunk and Link-group and you need to delete one of them from the Eth-Trunk, you must run the undo link-group command on the interface to be deleted and then delete the interface from the Eth-Trunk. Otherwise, services will be impacted.

Link-groups can be configured in virtual systems. The link-group IDs in the root system and each virtual system can be the same, but the number of link-groups of the root system and virtual systems cannot exceed the device specifications.

The interfaces of the root system and the interfaces of a virtual system can be added to the same Link-group, and the interfaces of different virtual systems cannot be added to the same link-group.

Example

# Add GigabitEthernet 0/0/1 to Link-group 1.

<sysname> system-view
[sysname] interface GigabitEthernet 0/0/1
[sysname-GigabitEthernet0/0/1] link-group 1
